The colourisation of the screen, like most marble and alabaster monuments, has suffered from repeated and careless washings. But the carvings preserve everywhere vestiges of paint and gilt, so that it is possible to reconstruct the scheme of colour. This is curious--generally blue and gold, with only a few touches of red and brown, which M. Marcel Dieulafoy suggests may be due to the artist’s desire to surround St. Tecla by the virginal and holy atmosphere which would be suggested by this manifold and unusual use of blue tones. This realisation of the spiritual expression of a legend is very characteristic of Spain, whose artists possessed as their greatest gift the power of rendering a story just as they felt it had happened. We owe the Tarragona altar-screen to a native Catalan artist. It was begun in 1426 by Pedro Juan de Vallfongona, who executed the bas-reliefs and statues of the first two stages, while at the same time the artist Guillermo de la Monta worked on the architecture and ornaments. But in 1436 Pedro Juan, gaining favour from the beauty of his work, was called to execute an altar for Zaragoza Cathedral, after which he only retained a sort of inspectorship over the work at Tarragona, which was finished by Guillermo de la Monta. Pedro Juan worked on the Zaragoza altar-screen until his death in 1447, aided by Pedro Garces, Guillermo Monta, and Pedro Navarro. For some reason the work was suspended for twenty-six years, when, on account of the great age of the original collaborators, it was entrusted to Gil Morlau, with Gabriel Gombao to aid him in the inferior parts. Finally the screen was completed and gilded and painted in 1480. The altar-screen of Zaragoza has some fine bas-reliefs; the most important is that of the centre, which shows the Adoration of the Magi. The Virgin, seated, presents her Babe to the Kings, figures of vigorous life and great dignity, who bend in worship as they offer their gifts; behind, a group of figures represent a crowd of onlookers. On either side of this central composition are bas-reliefs representing scenes in the Transfiguration, lives of the Virgin, and Ascension of Christ: these are the work of Pedro Juan. Another important retablo, which follows in date the work of Pedro Juan, is that in the Capilla de Santiago (Plate 56) in the Cathedral of Toledo. It is made of larch wood, and carved, gilded, and painted in the richest Gothic style. The bas-reliefs represent scenes in the New Testament; all the figures are life size. We owe this work to the artists Sancho de Zamora, Juan de Segovia, and Pedro Gumiel, and it was begun at the end of the fifteenth century. In the same chapel at Toledo are the six magnificent Gothic tombs of Don Álvaro de Luna, the work of Pablo Ortiz, one of the most famous carvers in the fifteenth century (Plate 58). Another interesting altar-screen is that in the Capilla de la Trinidad (Plate 59).
